Struct BaseFoldVerifierCompiler 

Source 
pub struct BaseFoldVerifierCompiler<F>
where
    F: BinaryField,
{ /* private fields */ }
Expand description

A compiler that creates BaseFold ZK verifier channels with precomputed parameters.

This compiler builds a single combined FRI over all oracles. ZK oracles configure FRI parameters for zero-knowledge mode (log_msg_len + 1 as the message length and log_batch_size = 1); non-ZK oracles take a flexible batch size with no mask.

Implementations§

Source§

impl<F> BaseFoldVerifierCompiler<F>
where F: BinaryField,

Source

pub fn new<H, Strategy>( merkle_scheme: &BinaryMerkleTreeScheme<F, H>, oracle_specs: Vec<OracleSpec>, log_inv_rate: usize, n_test_queries: usize, _arity_strategy: &Strategy, ) -> Self
where H: HashSuite, Strategy: AritySelectionStrategy,

Creates a new compiler with precomputed combined FRI parameters.

The merkle_scheme is consulted only for proof-size estimation while choosing the FRI parameters; it is not stored. Each oracle’s batch size is derived from its ZK flag: a ZK oracle fixes log_batch_size = 1 (message ‖ equal-length mask), a non-ZK oracle takes a flexible batch size. Requires at least one oracle spec.

Source

pub fn oracle_specs(&self) -> &[OracleSpec]

Returns a reference to the oracle specifications.

Source

pub const fn fri_params(&self) -> &FRIParams<F>

Returns a reference to the precomputed combined FRI parameters.

Source

pub fn max_log_domain_size(&self) -> usize

The dimension of the largest evaluation domain the combined FRI parameters need.

A prover builds its NTT domain context from this. The basis is not communicated because ReedSolomonCode fixes it: the Gao-Mateer basis of this dimension.

Source

pub fn create_channel<Channel>( &self, channel: Channel, ) -> BaseFoldVerifierChannel<'_, F, Channel>
where Channel: MerkleIPVerifierChannel<F, Elem: From<F> + 'static>,

Creates a ZK verifier channel over the given Merkle channel.

The returned channel drives all prover interaction through channel, opening oracles with this compiler’s oracle specs and combined FRI parameters. The caller constructs the Merkle channel, so it decides how commitments are received and verified.

Source

pub fn create_channel_from_transcript<H, Challenger_, T>( &self, transcript: T, ) -> BaseFoldVerifierChannel<'_, F, VerifierMerkleTranscriptChannel<T, Challenger_, F, H>>
where F: FixedSizeSerializeBytes, H: HashSuite, Challenger_: Challenger, T: BorrowMut<VerifierTranscript<Challenger_>>, Output<H::LeafHash>: DeserializeBytes,

Creates a ZK verifier channel over a transcript, for the common case.

The transcript may be owned or mutably borrowed. It is wrapped in a VerifierMerkleTranscriptChannel for the given hash suite. That channel is then passed to Self::create_channel.
